Pacific Oil Cooler Service

What Pacific Oil Cooler Service does

Pacific Oil Cooler Service, Inc. is a privately held, family-operated FAA-certified aviation repair station founded in 1961 and headquartered in a single facility at 1677 Curtiss Court, La Verne, California. The company buys, sells, exchanges, overhauls, services, and repairs aircraft oil coolers, heat exchangers, fuel heaters, valves, condensers, and evaporators, holding FAA Repair Station #RF3R813L and EASA Part 145 approval #EASA.145.5554 along with U.S. Army TACOM approved-source status under CAGE Code 6ZMA3. Its core technology is a proprietary 25-step FAA-approved overhaul and re-certification process featuring an exclusive ultra-sonic decontamination stage followed by multi-step high-pressure flushing to 100-micron and 10-micron thresholds, bead blasting, Iridite treatment, pressure testing, and Form 8130-3 certification; the company also offers a Re-Coring Service that installs factory-new core matrices under a 24-month unlimited-hour warranty (double the OEM warranty) and a Custom Fabrication Service using TIG welding for experimental, vintage, industrial, and automotive applications.

The company's product portfolio spans AERO-Classics FAA-PMA replacement oil coolers for Continental and Lycoming engines, Bird Dog/Stinson direct bolt-on replacements, PT-6 fuel heaters (alternatives to Pratt & Whitney Canada OEM), vintage oil coolers for WWII-through-Vietnam-era aircraft including AT-6, B-17, and P-51 Mustang platforms, and overhauled/exchange units for Bell, Sikorsky, Lockheed C-130, and Hawker Beechcraft applications. Pacific operates as the world's #1 volume distributor of AERO-Classics and Stewart Warner oil coolers and as a sales-led direct-to-customer business: orders are taken via a toll-free number (800-866-7335) and a request-a-quote website, with same-day shipping for orders placed before 4pm Pacific Time and overnight shipment available upon request. Pricing is quote-based and unit-priced, with exchange programs using refundable core deposits and a 25% expedite fee for rush turnaround; the 7–10 day normal overhaul turnaround is a key commercial lever.

The customer base is globally diversified across general aviation owners and pilots, FBOs, flight schools, engine shops, aircraft manufacturers, vintage warbird collectors and museums, European operators under EASA (including The Flying Bulls GmbH and Team Bonhomme), and U.S. government/military procurement channels — a structure that produces low customer concentration risk but also limits scalability through traditional enterprise contracts. With no disclosed funding, no headcount data, no acquisitions, and continuous single-site operation since 1961, the business profile is that of a mature, profitable specialty MRO with stable operations rather than an inflection-stage growth company.
